Aminomethyl-substituted organopolysiloxane as water-repellent and gloss-imparting coating for lacquered metal surfaces

Abstract

Abstract EXCELLENT HYDROPHOBIC PROPERTIES AND PLEASANT GLOSS ARE IMPARTED TO SOLID, ESPECIALLY SMOTH, SURFACES, FOR EXAMPLE LACQUER COATINGS OF THE BODIES OF MOTOR VEHICLES, BY APPLYING THERETO, ACCORDING TO THE INVENTION, NEW COATING COMPOSITIONS CONTAINING AS THE EFFECTIVE AGENT AN ORGANOPOLYSILOXANE WHICH IS AMINOMETHYL-SUBSTITUTED ON AT LEAST TWO OF ITS SILOXANE UNITS, CORRESPONDING TO THE FORMULA CH3-(SI(-CH3)(-CH2-N(-R)-R'')-O)N-(SI(-CH3)2-O)(P-N)- SI(-CH3)(3-A)-(CH2-N(-R)-R'')A OR TO THE FORMULA CH3-(SI(-CH3)(-CH2-NH(+)(-R)-R'')-O)N-(SI(-CH3)2-O)(P-N)- SI(-CH3)(3-A)-(CH2-NH(+)(-R)-R'')A (X(-))(N+A) IN WHICH P IS AN INTEGER GREATER THAN 25, A IS 0 OR 1, N IS AN INTEGER GREATER THAN (1-A) AND SMALLER THAN P/10, R AND R'', INDEPENDENTLY OF ONE ANOTHER, ARE HYDROGEN ATOMS OR ALKYL OR CYCLOALKYL RADICLS HAVING LESS THAN 9 CARBON ATOMS, AND X IS A MONOVALENT ACID RADICAL.
